This is a good product, it makes my nails much stronger. Easy to put on, makes a good base for varnish, worth the money

Does what it says on the tin
Love this varnish, I use it after I take off my gel nails to strength them and it works great. Leaves a lovely shine on your nails and lasts well.

Keep coming back to this clear, strengthener varnish.
I can"t live without this nail protector, tried so many other brands over the years ,but always keep coming back to this one. My only gripe with this varnish is that once the bottle is opened the contents only have a very short lifespan, generally having to throw away half a bottle of varnish. This varnish helps to protect my weak, ridged nails helping to promote a little growth, making my nails look nicer.

Great product!
Great nail hardener! I’m a nurse so I wash my hands all the time. Having grown my nails after biting them for years I found they were very brittle. Having read reviews I thought I’d try this product. I find it excellent. I’ve only been using it for a week and already my nails feel stronger. I recommend this. Good price too.

Not as good as expected, sadly.
Ok so, getting a good quality nail hardener in 2025, you would think should be easy right? Especially when it has the name 'Sally Hansen' on the bottle - a name known for good products. Sadly, I have found this to be lacking in performance and expectations. It has been demoted to a base or top coat. And my 'paper-nail' remains paper like....whilst I try and find something that works.

Hardened nails and shiny look
Took my acrylic nails off after 4 years. This has hardened my nails and helping my real nails grow and look shiny aswell.
